I agree with most of that Baz, but would question the average age of UK scene - over 60 now I would have thought.
It's difficult to predict what will happen, but contrary to Russ's wish, it was the rare soul events here in the UK that were thinning out pre Covid, especially some of the Nighters. Back to the age of the attendees again I guess and willingness to travel distances. If the foundations are weak it takes less for the house to fall down. We've said it for years but for that scene to survive there needs to be appeal for a younger generation. Apart from the 100 Club I don't see enough of that to sustain a scene going forward.
I know some are 'chomping at the bit' to get onto a dancefloor, as others have said a lot seem to be finding other ways of enjoying the music (podcasts, these so called "Bedroom DJs"., online alldayers etc.) or just other things to do with their lives, like gardening, bowls and walking ha ha!.
When a form of 'normal' returns, I reckon after an initial 'spurt' that there will be a lot less venues and for much of what survives the quality of music on offer will appeal to the lowest common denominator.
Sorry, but my glass is only half full now!
